THEODORE LINDENBERG, OF COLUMBUS, OHIO.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 794,236, dated July 11, 1905.

Application filed November 12, 1904. 7 Serial No 232,482.

To all whom, it may concern.-

Be it known that LTi-ruononn LINDENBERG, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to a new and useful improvement in acetylene-gas generators.

The object of the invention is to provide simple means of superior construction whereby a quantity of gas may be generated and stored up under pressure at a single'operation. By such an arrangement I obviate the delay and inconvenience of returning a tank to the charging-station to be refilled and also do away with the water-fed generators now commonly in use, which have been found to be more or less unsatisfactory.

It is also the object of my invention to provide a device of the character described that will be strong, durable, efficient, and simple, and comparatively inexpensive to make, and one in which the several parts will not be liable to get out of working order.

WVith the above and other objects in View the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of my improved device. Fig. 2 is a longitudinal sectional view. Fig. 3 is an elevation of the discharge end, and Fig. 4 is a transverse vertical sectional view taken on the line x of Fig. 2.

In the drawings, the numeral 1 designates a cylindrical tank, although it is to be understood that this tank may be otherwise shaped, which is formed with an integral bottom or end 2. Beyond its center or near its mouth or open end the tank is provided with a partition or head 3, suitably secured in the tank so as to form with the end2 a storage-compartment, having a length greater than the compartment which is formed between the said head and the mouth or open end of the cylinder. The partition 3 is formed in its central portion with a housing or pocket 4, proecting toward the end 2 and provided with apertures 5. This pocket is preferably filled with a suitable filtering material, through which the gas is caused to pass before entering the storage-compartment by way of the apertures 5. The mouth of the tank is formed with an outstanding annular flange 6, which forms a support for the closure or end plate 7,which is secured to the said flange by screwbolts 8 and separated therefrom by a gasket or packing-ring 9, which forms a tight joint therebetween. The end plate 7 is formed on its inner side with an annular receptacle 10, formed to fit snugly in the bore of the cylinder and provided in its center with an opening 11, having a diameter of such length as to allow a considerable portion of the receptacle to extend on all sides of the opening, thus providing means whereby a quantity of water may be contained in the receptacle until it is mixed with the carbid when the gas is generated. Projecting inwardly from the plate 7 is a carbid-cup 12, adapted to contain a charge of carbid, which when dumped into the water contained in the receptacle 10 is generated into gas. The end 2 is formed with a bosslike projection 13, from which projects a suitably-formed discharge-pipe 14, provided with a reduction-valve 15, by which the discharge of gas through the'said pipe may be regulated. I also mount upon the end 2 and in communication with the interior of the cylinder a suitable gage 16, whereby the pressure of the gas within the tank or cylinder may be determined.

The operation of my generator is as follows: The plate 7 being removed from the cylinder a quantity of water is placed therein and the carbid-cup 12 filled with a charge of calcium carbid. The plate is then placed in position on the cylinder and fastened thereto by the screw-bolts 8. The tank is now rolled or turned, which inverts the position of the carbid-cup 12 and dumps the carbid into the water contained in the receptacle 10. Acetylene gas is immediately generated,which gas passes out through the opening 11 into the compartment between the plate 7 and the partition 3, from which compartment it passes through the filtering material contained in the pocket 4 and through the openings or partitions 5 into the storage-compartment, which it fills. It is obvious that by such an operation a considerable quantity of gas is generated at one time, which may be drawn off through the pipe 14: as it is desired to use the same.

It is to be understood that the amounts of carbid and water are to be proportioned so that the same Will be entirely consumed when the gas is generated, otherwise satisfactory results Would not be produced.

When the gas generated has been consumed, it is merely necessary to recharge the tank or cylinder, which may be readily accomplished by simply removing the plate 7 and placing in their proper receptacles fresh charges of Water and carbid.

I do not Wish to limit myself to the exact details of construction herein set forth, as I may make various changes in the same Without departing from the spirit of my invention.

Having noW fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. In an acetylene-gas generator, a tank or cylinder, a transverse partition arranged in the tank and dividing the same into a generatingcompartment and a storage-compartment, a closure for the tank, a water-receptacle associated With the closure, and a carbid-receptacle associated with the closure and the carbidreceptacle arranged and constructed to dump its entire contents into the Water-receptacle When the tank is turned.

2. In an acetylenegas generator, a tank having an open end, a partition arranged in the tank so as to divide the same longitudinally into a storage-compartment and a generating-compartment, a closure for the open end of the tank, an annular Water-receptacle supported'from the closure and having an opening in communication With the generating-compartmen t, and a carbid-cup supported Within the Water-receptacle.
